WILLIAM MITOHAM, OF ALBANY, OREGON.

MILK-COOLER.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed June 17, 1908. Serial No. 439,024.

To all whom it may concern:

Be it known that I, \VILLIAM MI'roHAM, a citizen of the United States,residing at Albany, in the county of Linn and State of Oregon, haveinvented certain new and useful improvements in Milk-Coolers, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in milk coolers and aerators, andmore particularly one adapted to be attached to a hand separator toreceive the milk or cream from the same and conduct it to a suitabletank or receptacle.

The object of the invention is to improve and simplify the constructionand operation of devices of this character and thereby render the sameless expensive and more efficient.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a perspective View of theinvention; and Figs. 2 and 3 are longitudinal and transverse sectionalviews.

My invention comprises a trough-like body 1 of U-shape in cross sectionpreferably constructed from a single piece of sheet metal by bending thesame to provide a bottom 2 and two upright parallel sides 3, the upperedges of the latter being folded over upon themselves, as shown at at,to strengthen said sides and to provide a smooth upper edge for the opentop of the body. Formed in the sides 3 at a suitable distance beneaththeir upper edges are longitudinally extending, inwardly projectingsupporting ribs 5. The latter are formed by crimping the sides 3inwardly and they are arranged at opposite points upon the two sides soas to support a corrugated partition 6. They are inclined downwardlyfrom the upper end 7 of the body which is'closed by a plate or head 8 tothe lower open end 9 of the body so as to support the partition 6 in adownwardly incline'd position. The partition 6 is in the form of a metalsheet corrugated transversely, as shown at 10, and having its angularedges 11 supported upon and soldered to the angular or V-shaped ribs 5.The

upper end of the partition or corrugated plate 6 is soldered orotherwise secured at 12 to the plate or head 8 and its lower end 13 isextended downwardly and soldered to the bottom 2 of the body at a pointadjacent to the open end 9 of the latter.

From the foregoing it will be seen that the partition 6 divides the bodyinto a lower chamber or compartment let for cold water or any othercooling medium and an upper trough-like compartment 15 for the milk orcream, and that the top of said lower compartment forms the bottom ofthe trough in order that the milk or cream in passing over thecorrugated member 6 will be cooled and aerated.

Arranged in the bottom 2 of the body adj acent to the opposite ends ofthe compartment 1 1 are water inlet and outlet pipes 16, IT. The inletpipe 16 is larger in diameter than the outlet pipe 17 so that a slightpressure will be maintained in the compartment- 1i and the cold waterwill be kept at all times in contact with the under face of thecorrugated partition or plate 6. Upon the upper end of the body isprovided a bail 18 which may be engaged with the spout of a separator toseparate the cooler.

In use, cold water is forced through the chamber 14 while the milk orcream from the separator is discharged into the upper end of the troughor chamber 15 so that the milk or cream in passing over the transversecorrugations in the bottom of said trough will be aerated and cooled bythe cold water in the compartment 14. The milk or cream is dischargedfrom the open end 9 of the body into a suitable vat or receptacle.

Having thus described my invention what I claim is:

A device of the character described comprising a U-shaped body having abottom wall, parallel side walls and an end wall or head, the side wallshaving inwardly extending supporting ribs formed by crimping the same, atransversely corrugated partition plate arranged between the side wallsand supported by and secured to said ribs, one end of the plate beingsecured to said end or head of the body and its other end being securedto the bottom of the body adjacent to the open end of the latter, saidpartition dividing the body into a lower chamber for 2: I w r 913,418
